Dyson Airstrait Straightener -Onyx Black and Gold - Special Edition - New. Your routine, simplified. The Dyson Airstrait™ dries and straightens hair simultaneously. Take hair from wet to a finished look – with one machine. Dyson's latest hair care technology uses high-pressure airflow to straighten hair as it dries. Air is precisely heated and projected evenly through the tress as you style – with no heat damage.¹ Intuitive airflow when you need it. Your machine senses when hair is between the arms and automatically drops to low airflow when it's not – for quieter, more efficient styling. Engineered to maintain hair strength and protect shine.³ Dyson's latest hair care innovation combines their expertise in airflow with everything we've learned about hair styling to pioneer a new way to straighten – with no heat damage.¹ Airflow is projected downwards at a 45° angle to create the tension needed to align hair for a smooth end style – with less damage and breakage.²
